Modelling and control of robot locomotion in mixed terrains

Summary:

This PhD project will investigate modelling and control methods for robot locomotion in mixed dry and submerged environments, in or over yielding terrains. Candidates from robotics-related disciplines with a strong control systems background are invited to apply.

The work will be part of the EU-funded project PIPEON, which will investigate robotics and AI for inspection and maintenance of sewer pipes.

Description:

The research

Accurate and stable locomotion is challenging but crucial for mobile robots in dynamic unstructured environments (such as sewers), that contain a combination of solid ground, loose or thick sediment layers. Additionally, locomotion systems that use reconfigurable actuators with non-traditional morphology, optimized for locomotion in these environments, may increase the complexity of the robot’s control.

In this context, this PhD project will investigate modelling and control methods for robot locomotion in these challenging terrains, aiming to develop a robust control algorithms for locomotion. In particular, the focus is on modelling and control between the dynamic environment and the robot’s locomotion system, and on evaluating the controller performance not only in simulation but also in the physical sewer pipe environment.

The modelling effort will take into account the locomotion system’s states and control inputs, as well as the condition of the terrain, to estimate the behaviour of the robot as it interacts with the dynamic environment.

The candidate will work in the EU-funded project PIPEON with 12 partners (academic, industrial and public) and will contribute towards integration, testing and validation of the methods and prototypes of the project.

About the department

The Centre for Biorobotics (https://taltech.ee/en/biorobotics) specializes in research and development of robotics and sensing. On the robotics side, we are focusing on development of

locomotion and control in underwater and multiphase environments, where conventional terrestrial and underwater platforms are underperforming. In connection with robotics, we are

focusing on developing bioinspired sensing methods in combination with conventional tools to improve situational awareness and navigation performance of our robots. Apart from robotics,

we are also applying the bioinspired sensing methods in water flow sensing in natural environments (rivers, coasts etc.).

Our core competences are as follows:

•      Development and manufacturing of underwater robotic platforms

•      Robot locomotion and control in mixed environments

•      Underwater sensing with applications in natural environments

•      Mapping and navigation in unstructured environments

Some of our research activities include:

•      Developing new principles of locomotion using soft and compliant actuators

•      Control and navigation of underwater robots in flow, surges, and waves

•      Robot sensing in underwater environments

•      Distributed sensor networks for measuring and characterizing flow and turbulence

•      Development of underwater sensor systems for safe navigation in harbors

•      Measuring extreme flows including sub-glacial flows, rivers etc.

•      Environmental sensors for monitoring and protection of critical infrastructure
